Iron Deficiency Anemia

Anemia iron deficiency is the most common type of anemia, which may affect newborns and adults. It is also called martial anemia. It is a condition in which the body does not have adequate levels of iron and this impairs the transport of oxygen through the blood causing, among other things, tiredness and shortness of breath.

What is iron deficiency anemia?

Iron is a fundamental mineral for some biological functions, including the formation of hemoglobin. When there is a lack of iron, caused by a poor intake with food, by problems in absorption, by blood loss, the production of hemoglobin is insufficient and this causes a poor circulation of oxygen through the body. It affects all age groups, mainly children, adolescents, women of childbearing age, pregnant and breastfeeding.

What are the causes of iron deficiency anemia?

Iron deficiency anemia occurs when the body does not have sufficient iron levels to produce hemoglobin. Hemoglobin is a protein found in red blood cells that binds to oxygen and carries it through the blood to power muscles, tissues and organs. The causes of a lack of iron can be different:

  • Hemorrhages and bleeding

    Blood loss, even if not noticeable or internal, can lead to a reduction in iron levels. This occurs frequently in women of childbearing age during menstruation. Bleeding can also be occult, slow and chronic, for example when blood loss occurs inside the body, in correspondence with a hiatal hernia, a colorectal polyp, a peptic ulcer, or a tumor.

  • Poor intake in nutrition

    Anemia can be caused by a diet in which iron intake is drastically reduced. This is a fairly rare condition, as a varied diet allows you to receive the right iron content, but it can be linked to eating disorders or too drastic diets.

  • Poor iron absorption

    In some cases there may be metabolic defects that do not allow the iron introduced with food to be sufficiently absorbed. This happens, for example, in the presence of chronic diseases, like chronic intestinal diseases (ulcerative colitis and Crohn’s disease) or celiac disease, in which damage to the intestinal villi compromises the ability to “extract” iron from food, diverticula, colon tumors and stomach.

  • Pregnancy and breastfeeding

    These are critical phases for iron reserves, because they require a greater need for iron for the development of the fetus.

  • Surgical interventions

    Interventions that have resulted in the removal or bypass of parts of the intestinal tube can reduce the absorption capacity of iron.

What are the symptoms of iron deficiency anemia?

The symptoms of an iron deficiency anemia change over time. Initially they may be mild, because the body supplies itself from the iron deposits present in the form of ferritin. As the deficiency continues, symptoms intensify and can occur:

Iron Deficiency Anemia Diet

  • extreme fatigue and weakness (asthenia)
  • pallor
  • irritability
  • headache
  • insomnia
  • shortness of breath
  • chest pain
  • vertigo and dizziness
  • cold hands and feet
  • brittle nails
  • hair loss
  • acceleration of the heartbeat
  • burning in the throat
  • poor appetite
  • tingling in the legs

How to prevent iron deficiency anemia?

Prevention is very important to avoid iron deficiency anemia. A varied diet should be followed, including iron-rich foods such as red meat, pork, green leafy vegetables, nuts, chicken, seafood, beans. These foods can be accompanied by foods with a high content of vitamin C that improve iron absorption. Particular attention should be paid to children, pregnant and breastfeeding women.
